Philips TV turns on with sound no backlight
I got this problem with my tv, when I power the tv on the logo appears for 2-3 seconds and then it's all black. The sound is still there, the ambilight reacts normal, but no image.
What could this be? I know a part of the LED strip is broken and I already bought a new strip, but I don't know if this would fix it because my other Samsung TV had a defective LED strip to but still had a picture. I also couldn't find any bulged capacitor or anything.
The only difference with these tv's are the Samsung is direct-LED and the Philips edgelit.
Model is: 42PFL6678k/12
EDIT: Picture and video
I got the tv working again, but the light doesn't cover the whole screen?!?
Now i'm stuck with what to do, because I already replaced the tcon board and led strip.
Is this a good question?
